Aircrafts look the same then 70 years ago
1. Airliner’s fuselages didn’t change for 70 years All current aircraft are Tube & Wing designs. A wing, which generates lift, a tube-like fuselage, which holds the load, and a balancing tail. Only small improvements were made to noses, cockpit windows, wing-root fairings and tail-cones. However, these can not improve much further.
2. Revolutionary designs are required for greater efficiency

Much more efficient technologies are already invented. Without a decisive regulatory and economical stimulus, these will not materialise. Because of CORONA and expected low fuel prices for a long time thereafter, aircraft manufacturers have axed all plans for more efficient aircraft,
